Aromatic enyne compounds and their synthesis

Abstract

Difunctional aromatic enyne compounds are prepared by the catalytic coupling of substituted monoethynyl compounds. The compounds are useful as monomers in polycondensation reactions for the preparation of high molecular weight, thermally stable thermoplastic polymers. On thermal treatment of the polymers, the enyne groups along the polymer backbones react by interchain reactions to provide the solvent and craze resistance required for application as structural materials.

We claim: 
     
       1. A difunctional aromatic enyne compound having the following formula: ##STR11## in which R is NH 2 , OH ##STR12## 
     
     
       2. The compound according to claim 1 in which R is NH 2 . 
     
     
       3. The compound according to claim 1 in which R is OH. 
     
     
       4. The compound according to claim 1 in which R is ##STR13##
